Champion's Helm

While wearing this helm, you gain a +2 bonus
to melee weapon attack and damage rolls, and
a +2 bonus to AC. Additionally, while wearing
this helm, any time you are targeted by a magic
missile spell, or a spell that requires a ranged
attack roll, roll a d20. On a roll of 1 to 4, you are
unaffected. On a 1, you are unaffected, and the
effect is reflected back at the caster as though it
originated from the wearer, turning the caster
into the target. Otherwise, the wearer is affected
as no
